FIELD OF INVENTIONEmbodiments of the invention are generally related to cloud services, and are particularly related to a system and method for insulating a web interface application from underlying technologies in a cloud-based integration service.
BACKGROUNDThe rapid shift from on-premises applications to a hybrid mix of Software-as-a-Service (SaaS) and on-premises applications has introduced challenges for companies attempting to integrate enterprise applications. Integration platform as a service (iPaaS) can provide a set of cloud-based tools to address these challenges. An iPaaS platform can provide a design time for developers to design, deploy and monitor integration projects. However, these integration projects can be tied to particular runtime engine, and cannot be deployed to a different runtime engine without additional work.
SUMMARYIn accordance with an embodiment, described herein is a system and method for providing an abstraction layer that insulates a web interface application from underlying technologies in a cloud-based integration service. The abstraction layer can include an application programming interface that exposes a plurality of services to the web interface application, for use in the entire life cycle of an integration project. The web interface application is agnostic of the underlying frameworks that persist the integration project, and the runtime engines that are to execute the integration project. The application programming interface can persist the integration project in a runtime-engine-neutral format, and can transform the integration project from the runtime-engine-neutral format to a runtime-engine-specific format at deployment time.
Integration platform as a service, for example, Oracle Integration Cloud Service (ICS), can provide a cloud-based platform for building and deploying integrations flows that connect applications residing in the cloud or on-premises.
As shown in
In accordance with an embodiment, a plurality of application adapters 113 can be provided to simplify the task of configuring connections to a plurality of applications, by handling the underlying complexities of connecting to those applications. The applications can include enterprise cloud applications of the ICS vendor (for example, an Oracle RightNow) 105, third-party cloud applications (for example, Salesforce) 103, and on-premises applications 119. The ICS can expose simple object access protocol (SOAP) and representational state transfer (REST) endpoints to these applications for use in communicating with these applications.
In accordance with an embodiment, an ICS integration flow (or ICS integration) can include a source connection, a target connection, and field mappings between the two connections. Each connection can be based on an application adapter, and can include additional information required by the application adapter to communicate with a specific instance of an application.
In accordance with an embodiment, an ICS integration flow can be defined in an ICS project, which can include a structured set of artifacts, for example, metada, Java Connector Architecture (JCA) files and web service definition language (WSDL) files. An ICS project can be deployed and executed in the ICS runtime, and can be used to integrate cloud applications and on-premises applications. As such, an ICS project is an integration project. Throughout the document, the terms “ICS project” and “ICS integration project” are used interchangeably. Both terms can be used to refer to an integration project.
Abstraction Layer
As described above, an ICS can include a web UI application for ICS developers to design ICS projects, and a runtime for executing the projects.
During the life cycle of an ICS project, a developer often needs to use a plurality of interfaces. For example, during the development phase, the developer can perform CRUD (create, read, update, and delete) operations on the project. During the deployment phase, the developer can compile and deploy the project. These operations can be performed in different interfaces. In addition, an ICS project can be developed in a format specific to a particular runtime engine, and cannot be reused for a different runtime engine without additional work.
In accordance with an embodiment, the system can provide an abstraction layer that insulates a web interface application from underlying technologies. The abstraction layer includes an application programming interface that exposes a plurality of services to the web interface application, for use in the entire life cycle of an integration project. The web interface application is agnostic of the underlying frameworks that persist the integration project, and the runtime engines that are to execute the integration project. The application programming interface can persist the integration project in a runtime-engine-neutral format, and can transform the integration project from the runtime-engine-neutral format to a runtime-engine-specific format at deployment time.
In accordance with an embodiment, the abstraction layer can reside between the web interface application, and one or more runtime engines in the ICS runtime, thereby insulating the ICS web interface layer from the underlying integration technology.
In accordance with an embodiment, a plurality of handlers can be provided, each for a particular runtime engine. A handler specific to a runtime engine can be used to transform an ICS project from a runtime-engine-neutral format to a format specific to the runtime engine.
Additionally, the abstraction layer can be used to generate and validate ICS packages, export and import an ICS project, bootstrap the persistence store with pre-defined ICS project and data, and move ICS data between ICS project instances.
As shown in
In accordance with an embodiment, the abstraction API can provide a plurality of services using a plurality of classes/objects, for example, a persistence manager 217 and an operation manager 219, to insulate these functionalities from the underlying technologies (for example, persistence frameworks and runtime engines), which can provide flexibility and code reuse when the underlying technologies change.
In accordance with an embodiment, during the development phase of an ICS project, the developer can create a plurality of ICS objects (for example, connection objects, and integration flow objects). These objects need to read, updated or deleted. A plurality of persistence frameworks 223 can be plugged into the abstraction layer, and can be used by the operation manager, to perform the CRUD operations without the knowledge of the web UI application. The operation manager provides a set of interfaces that can insulate the exposed functionalities from the persistence framework configured to perform the functionalities.
As further shown, the abstraction layer can further include a plurality of project templates (for example, OSB templates), and a project handler 227 that can automatically select a runtime-engine-specific handler (for example, OSB handler), based on a user's selection of a particular runtime to host the ICS project. The selected runtime-engine-specific handler can convert the runtime-engine-neutral project retrieved by the operation manger from a persistence store, to a runtime-engine-specific project using one or more project templates 225. The operation manager can deploy 233 the runtime-engine-specific project to a particular runtime engine. By developing an ICS project in a runtime-engine-neutral format and converting it into a runtime-engine-specific format at deployment, the abstraction layer effectively insulates the web UI application from the runtime engines.
In accordance with an embodiment, the abstraction API further includes a runtime metrics presenter 221, to format and display runtime metrics 231 collected by APIs exposed by the ICS runtime. For example, the runtime metrics can include numbers of transactions and failed transactions per second for a given ICS integration flow, logging information for each successful invocation, activity stream showing, e.g., during the last 20 records. The exposed API by the ICS runtime can also be used to download transaction log files, and to retrieve user-specified requests for a particular type of runtime metrics.
As illustrated in
In accordance with an embodiment, a runtime-engine-neutral ICS project can represent a project structure that is not specific to a particular runtime/integration engine, and can be defined by the web UI application. A runtime-engine-neutral project can include metadata defined in an XML format that represents configuration such as source applications, target applications, integration patterns, and schemas.
In accordance with an embodiment, an ICS project class can represent a runtime-engine-neutral format project, and can encapsulate the required metadata. An instance of the ICS project class (ICS project artifacts 314) can be stored to the persistence store.
In accordance with an embodiment, the persistence manager can perform session management 311 and resource locking/unlocking 313 while an ICS project is being developed. The persistence manager can keep tract of the status of each resource (e.g., files and metadata), and prevent a developer from unlocking a resource that another developer locks.
In accordance with an embodiment, different persistence frameworks, for example, OSB configuration framework, and Oracle Enterprise Repository (OER), can be plugged into the persistence manager, thereby insulating the web UI application from the persistence frameworks.
In accordance with an embodiment, the operation manager can be used to activate an ICS project.
Without the abstraction layer, an ICS project needs to be activated by explicitly performing a “build” action to generate an enterprise archive (EAR) file from the ICS project, selecting the EAR file from a web interface to deploy it, and using a third interface to monitor the deployed project. The abstraction layer can combine the EAR file generation, and deployment and monitoring of the ICS project into a single step in a particular interface.
In accordance with an embodiment, the Activation button can be placed beside an ICS project name. When the button is clicked, an ICS developer can be prompted to select a particular runtime to deploy the ICS project. In response to the selection, the operation manager can retrieve 411 the runtime-engine-neutral project from the persistence store using the persistence manager, transform the ICS project into a runtime-engine-specific format, generate an EAR file, and invoke APIs exposed by the specific runtime engine, for example Oracle Service Bus runtime engine (OSB), to deploy the EAR file thereon.
In accordance with an embodiment, the operation manager can invoke the project handler, which can select a runtime-engine-specific handler to transform the project, based on the runtime selected by the ICS developer.
As shown in
In accordance with an embodiment, a plurality of runtime-engine-specific handlers can be provided by the abstraction layer, for example, an Oracle Service Bus (OSB) handler 427, and a business execution process language (BPEL) handler 447. When the OSB handler is selected, the OSB handler can retrieve OSB templates from, e.g., a database, and use the templates and associated metadata to add specifics needed for the ICS project to run on an OSB runtime engine. A plurality of methods can be used to transform the ICS project using the retrieved templates and metadata.
In accordance with an embodiment, after the project is deployed, monitoring of the deployed project can be performed through the same user interface where the activation button described above is located.
In accordance with an embodiment, the ICS runtime can expose a set of APIs used to display runtime metrics, such as number of transactions and failed transactions per second for a given ICS integration flow, logging information for each successful invocation, activity stream showing, e.g., the last 20 records. The exposed API can also be used to download log files for all the transactions, and to receive user-specified requests for a particular type of runtime metrics.
As shown in
As further shown in
In accordance with an embodiment, the operation manager can receive (step 516) the created packages, and invoke a project handler 508 to create a transformed project (step 518). The operation manager can further invoke a runtime deployment bean 509 to deploy the transformed project (step 521).
As described above, a click on a button to activate the ICS project can perform the steps of retrieving the runtime-engine-neutral project, creating project packages (compiling the project), transforming the project into a runtime-engine-specific project, and deploying the transformed project.
In accordance with an embodiment, after the ICS web UI application receives an indication that the ICS project has been successfully deployed (step 525), a monitoring screen can be automatically displayed, wherein requests for runtime metrics (step 526) can be sent to the ICS runtime hosting the deployed project. Runtime metrics can be received (step 527) by the monitoring interface, and displayed in various formats (for example, bar charts).
As shown in
At step 613, an abstraction application programming interface (API) is provided, the abstraction API exposing a plurality of services to the web UI application, for use in designing, deploying and monitoring an ICS project.
At step 615, the ICS project is persisted in a runtime-engine-neutral format.
At step 616, at deployment time, the ICS project is converted into a format specific to one of the runtime engines in the ICS runtime.
